Answer:
1/2 the area of the quadilateral ABCD
Step-by-step explanation:
Given a quadilateral ABCD a diagonal BD is drawn.
The area if the triangle formed should always be the half of the area of the quadilateral.
This rule works for quadilateral with similar sides and shape where a diagonal that bisect the shape equally can be drawn
Examples of these quadilateral is
Square
Rectangle
Rhombus
6^3. 216. When using chance, take the possible outcomes(six for a die) and raise it to the power of the number of repetitions.
Is this question correct? is it thousand or thousandth? and does the comma signify a decimal point?
Answer:
Step-by-step explanation:
1) ΔCPD & ΔEPF
∠CPD = ∠EPF { Vertically opposite angles}
∠CDP = ∠PFE {CD║EF, FD is transversal, Alternate interior angles are equal}
ΔCPD ≈ΔEPF {AA criteria for similarity }
Cross multiply
EF * 15 = 27 * 7.5
EF = 27 * 0.5
EF = 13.5 cm
ii) EF // AB, so Triangles ACB & ECF are similar triangles
AC = 37.5 cm
It's about 20 units
Hope this helped :)
